A method of verifying display of primary visual information on a screen of an electronic visual display device in which primary visual information is displayed on the screen of the display device. Visual verification information is simultaneously displayed at a verification location of the screen. The verification location is monitored using an optical detector to determine if the visual verification information is displayed. Display of the primary visual information is verified if it is determined that the verification information has been displayed.

2. The method of claim 1, further including displaying said visual verification information at at least one verification location on a display area of said screen, and monitoring said at least one location using said at least one optical detector, and wherein said at least one verification location may be located at a peripheral part of said display area.
3. The method of claim 1, wherein said at least one input signal comprises data representing said primary visual information, wherein said primary visual information may comprise any one or more of: text; one or more image; one or more animation; one or more video, and wherein said at least one input comprises data representing said visual verification information, said visual verification information comprising any visual information that may be displayed on the screen and be detectable by said at least one optical detector, and wherein, optionally, said data representing said visual verification information is included in, added to, or associated with, data representing said primary visual information.
4. The method of claim 1, further including verifying display of said primary visual information by determining that said visual verification information is detected on said screen by said at least one optical detector.
5. The method of claim 1, wherein said comparing involves using one or more adjustable similarity threshold.
6. The method of claim 1, wherein each part typically comprises data representing a colour, a pattern or a tone.
7. The method of claim 1, wherein said at least one input signal includes data for causing said visual verification information to be displayed on said screen as foreground visual information, optionally overlying a portion of said primary visual information, and/or wherein said at least one input signal includes data for causing said visual verification information to be displayed on said screen separately from said primary visual information.
8. The method of claim 2, further including adjusting the position and/or size of said at least one verification location on said display area of said screen to match the location of said at least one optical detector.
9. The method of claim 5, wherein a number of said multiple instances is adjustable.
